I have read that engines with bushings need more oil than engines with roller bearings, it make sense to me but I have no personal experience with that issue.
That sounds correct, it was something to that tune. The older lawnboys must have been bushing engines that couldn't survive with less oil...
Really a bushing? That would be a really [censored] bearing. There are needle, ball and roller bearing, never heard of a bushing in an OPE engine, but never had a Lawnboy. If they have bushings, then I never will.
